All the levels of backslashes you have to put before delimiters. For
example, if you want to put a two minutes duration in a filter graph
description, you can not write "testsrc=d=2:00", because the colon will
delimit the option. You have to write a largish number of backslashes in
front of the colon. It becomes ever worse when nesting values: think of
colons inside the localtime expansion inside the text option of the drawtext
filter.

I believe we could avoid that almost entirely.
